Abstract
The invention discloses a high-strength composite ice bag and a temporary filling method. The ice bag is connected with a rapid freezer, and comprises a thermal insulation layer, a high-strength silk chemical fiber layer, a fiber reinforced plastic layer, a water injection hole and a drainage hole, wherein the thermal insulation layer is an outermost layer of the ice bag; the high-strength silk chemical fiber layer is a middle layer of the ice bag; the fiber reinforced plastic layer is an internal filler of the ice bag; the top end of the ice bag is provided with the water injection hole; the bottom end of the ice bag is provided with the drainage hole. The temporary filling method of the ice bag comprises the following steps: (1) arranging the ice bags on the rear side of a working face support according to a certain inter-row space; (2) filling the ice bags by using mine water; (3) starting the rapid freezer to rapidly freeze water in the ice bags; (4) supporting a gob roof by the frozen ice bags at a rational inter-row space to realize filling of a gob. The high-strength composite ice bag is low in manufacturing cost, the filling process is simple, the coal mining cost is reduced, and the overall labor efficiency is high.
Description
Technical field
The present invention relates to mine goaf filling technique, be specially a kind of high-strength compound ice bag and interim fill method thereof.
Background technology
Mine needs to carry out filling to goaf adopting sky coal seam, and the method for mining by the way of filling is the common method that mine roof management and " three next on " mine, and the method for mining by the way of filling can be divided into manpower filling, filling-up pneumatically, dry powder filling, hydraulic fill etc. according to filling power.Wherein hydraulic fill is most widely used, and in hydraulic fill, is initially not containing the hydraulic filling of adhesive material, has developed consolidated fill later, and the concentration of obturation is progressively improved, progressively developed into the paste-like backfill of high concentration, paste body filling.And existing filling technique, process procedure is too much, and process is complicated, and equipment requirement is higher, needs the packing material of at substantial in production; Work plane coal mining activity is affected when filling operation; Overall efficiency is low, and the cost of output of coal per ton raises.
Summary of the invention
The object of the present invention is to provide a kind of high-strength compound ice bag and interim fill method thereof, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the invention provides following technical scheme:
A kind of high-strength compound ice bag, comprise ice bag, described ice bag is connected with quick freezing machine, described ice bag comprises insulating layer, high strength silk vulcanized fibre layers, fiber-reinforced plastic layer, water injection hole and drain hole, described insulating layer is the outermost layer of ice bag, and described high strength silk vulcanized fibre layers is the intermediate layer of ice bag, and described fiber-reinforced plastic layer is the inside stuffing of ice bag, water injection hole is left on the top of described ice bag, and drain hole is left in the bottom of described ice bag.
An interim fill method for high-strength compound ice bag, comprises the steps:
(1) ice bag is arranged at scaffold working face rear by array pitch between certain;
(2) mine water is adopted to inject ice bag, until ice bag to be filled rear stopping water filling by the water injection hole on ice bag top;
(3) quick freezing machine is opened by the water snap frozen in ice bag;
(4) the freezing ice bag completed is supported goaf top plate with array pitch between reasonably, realizes goaf filling, and leave enough spaces, for permanent completion method with control completion method effective transport channel be provided.
As the further scheme of the present invention, interim fill method, for bear filling task at the appointed time, dissolves ice in ice bag when not needing to fill.
As the further scheme of the present invention, described control completion method is the deflection of controlroof, and above ground structure inclination or earth's surface can not be caused intermittently to sink.
As the further scheme of the present invention, described permanent completion method is by Roof Control, cause top board to sink and form permanent support transport of materials passage, between the spacing of ice bag, settling adhesive tape conveyor to transport permanent packing material sand, loess, cement and gypsum complete permanent filling.
Compared with prior art, advantage of the present invention: this high-strength compound ice bag cost is low, its fill process is simple, only need quick freezing machine, water in mine is adopted to be that filler, filling process holistic cost are low, packing job does not affect work plane coal mining activity, and reduce mining costs, overall efficiency is high.
Accompanying drawing explanation
Fig. 1 is high-strength compound ice bag schematic diagram of the present invention;
Fig. 2 is high-strength compound ice bag schematic cross section of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further elaborated.
As shown in Figure 1-2, a kind of high-strength compound ice bag, comprise ice bag 1, described ice bag 1 is connected with quick freezing machine, described ice bag 1 comprises insulating layer 11, high strength silk vulcanized fibre layers 12, fiber-reinforced plastic layer 13, water injection hole 14 and drain hole 15, described insulating layer 11 is the skin of ice bag 1, described high strength silk vulcanized fibre layers 12 is the intermediate layer of ice bag 1, described fiber-reinforced plastic layer 13 is the inside stuffing of ice bag 1, water injection hole 14 is left on the top of described ice bag 1, and drain hole 15 is left in the bottom of described ice bag 1.
An interim fill method for high-strength compound ice bag, comprises the steps:
(1) ice bag is arranged at scaffold working face rear by array pitch between certain;
(2) mine water is adopted to inject ice bag, until ice bag to be filled rear stopping water filling by the water injection hole on ice bag top;
(3) quick freezing machine is opened by the water snap frozen in ice bag;
(4) the freezing ice bag completed is supported goaf top plate with array pitch between reasonably, realizes goaf filling, and leave enough spaces, for permanent completion method with control completion method effective transport channel be provided.Reasonably, array pitch not only forms enough support forces top board is not caving, and saves the usage quantity of ice bag, and be packing material is all filled completely whole goaf relative to other interim fill methods, save material, cost is low.
Interim fill method, for bear filling task at the appointed time, dissolves ice in ice bag when not needing to fill.Described control completion method is the deflection of controlroof, and above ground structure inclination or earth's surface can not be caused intermittently to sink.Described permanent completion method is by Roof Control, causes top board to sink and forms permanent support transport of materials passage, settles adhesive tape conveyor to transport permanent packing material sand, loess, cement and gypsum and complete permanent filling between the spacing of ice bag.
Utilize ore deposit to enter interior waste water snap frozen by facts have proved to mine goaf, adopt ice bag to fill, obturator compressive strength is high, can reach more than 220Mpa, reaches safety in production requirement, reduces cost of production of knowing clearly.
Above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
